6. Adjust the input voltage from the tension
controller to the Channel “A” input observing
the “RED” and “GREEN” LED’s. If a 24 volt
system is being commissioned, then only the
“GREEN” LED should be functional unless
there is a problem with the controller, brake,
or wiring.
7. If no other indications are present on the
LED’s then the system is functioning properly.
The intensity of the “GREEN” LED does not
change with the amount of output current
being supplied to the brake.
8. If other LED indications are present, proceed
to the troubleshooting section on page 17 to
determine cause and appropriate action to
take.
9 Adjust the input voltage from the tension
controller to the Channel “B” input if a brake
is connected to the Channel “B” output
observing the “RED” and “GREEN” LED’s. If
a 24 volt system is being commissioned, then
only the “GREEN” LED should be functional
unless there is a problem with the controller,
brake, or wiring.
10. If no other indications are present on the
LED’s then the system is functioning properly.
The intensity of the “GREEN” LED will not
change with the amount of output current
being supplied to the brake.
11. If other LED indications are present, proceed
to the troubleshooting section on page 17 to
determine cause and appropriate action to
take.
48 Volt System
1. Prior to applying power, double check all
wiring between Tension Control and Driver,
Driver and Brake or Brakes, and 48 Volt
Power Source and Driver.
2. Once connections are checked and
confirmed that all wiring is correct, turn power
on to the Power Supply and Controller and
observe “RED” and “GREEN” LED Indicators
on the Driver.
3. If everything is normal, then the “GREEN”
LED will be on and “RED” LED’s will be off.
Any other indication of the “RED” and
“GREEN” LED’s, refer to the troubleshooting
section, page 17 of the manual for
troubleshooting and diagnostics.
4. If drive is functional and no problems are
noted, then the anti-residual output to the
brake or brakes needs to be adjusted
accordingly. Adjust the anti-residual output
for Channel “A” as follows:
4a. Using a digital DC Voltmeter, connect the
positive lead to terminal 1 and the
negative lead to terminal 2 of the
MCS2000-DRV2 for Channel “A” input.
4b. Adjust the Tension controller being
used to give a 0 VDC reading on the
Channel “A” input.
4c. Using a small screwdriver, rotate the
anti-residual potentiometer “A” fully
counter-clockwise so the output
voltage to the brake is zero level.
Voltage can be measured to the
Channel “A” brake on terminals 5 and
6 of the MCS2000-DRV2. Terminal 5
is positive, and terminal 6 is
negative. Note that the “GREEN” LED
for Channel “A” is flashing at this time.
